Application filed Oetolo To all whom it may concern.'

Beit known that I, ERNST zen of the United States, and a resident of the city of Ossining, county of lVestchester, and State of New York,hav einvented certainv new and useful Improvements in Brushes, of which the following is a specilication.

My invention relates to improvements in brushes especially adapted for use as flue brushes and has for its object the provision of an improved construction of this character which is simple and efficient in use.- I The invention consists in the combination and arrangement of parts hereinafter def scribed and claimed. r

The invention will be best understood by reference to the accompanying drawing, forming a part of this specification, and in which- Figure 1 is a longitudinal section of a brush embodying my invention, Fig. 2, an end view of the same, Fig. 3, a. detailed view illustrating brush bristles in one stage. of manufacture, and Fig. y View. illustrating brush bristles in 4the fina-l stage of manufacture. j

The preferred form of construct-ion as illustrated threaded stem 5 in the form ofa long bolt threaded at one end for a considerable distance and provided with a head 6 at the other end. A nut and coperates with and vfasten the brush a washer 8 to imprison bristles 9 on said stern as indicated in Fig. 1. The brush elemen'; proper is formed of a large number of tufts of bristles 9, said tufts of bristles being preferably formed of sections of Manila rope and being doubled about two binding cords or cables 10 arranged adjacent and parallel to each other as best indicated in Fig. 3. The ends of=bristles 9 are then doubled between the cords 1() as indicated in Fig. 4. A large number of bristle tufts are thusv arranged on the cords 10 and the ends of the cords tied together thus securing the bristles to the cords and in effect forming a long string of bristles. This string of bristles is then wound about the stem 5 helically with the cords 10 adjacent said stem and the bristles projecting radially therefrom thus securely binding The nut 7 and washer 8 are then tightened against the corresponding end of the bristles OLsoN, a citi- 4, another 'detailed in the drawing comprises av Specication of Letters Patent.

stem and completing the brush proper. The

the

brush is secured to an operating handle 0f.'

stem 11 by means of an ordinary pipe coupling 12.- By this arrangement a brush is provided vof great durability and flexibility in use and which is also capable of economical manufacture.` j

While I have illustrated and described the preferred form of lconstruction for carrying my invention into effect, this is capable of variation and modification without departing from the spirit therefore, 'do not wish to be limited to the precise details of construction set forth, but desire to avail myself of such variations and modifications 4as come within the scope of the appended. claims.

Having described my invention what desireto secure by Letters Patent is:

1. A binding for brush bristles consisting of the invention. l, i

of two elongated adjacent binding elements; and bristlles doubled about and between said f Aso brush bristles consisting bristles doubled about and between said' binding elements, and said binding elements being coiled helically, substantially as described.

3. A brush comprising a central stem; a

brush element consisting of two elongated adjacent binding elements and bristles doubled about and betweensaid binding ele-4 ments, said binding elements being wound about said stem helically; and means securing lsaid binding elements and bristles to said stem, substantially as described.

4. A brush comprising a central threaded stem; al vbrush element consisting of .two elongated adjacent binding elementsl and bristles doubled about and between said binding elements, said binding elements being wound about said stem helically; .and a'nut securing said binding elements and bristles to said stem, substantially as described.

lIn testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
